Galvanized steel plate is coated with a layer of metallic zinc on the surface

Galvanized steel plate is coated with a layer of metallic zinc on the surface of the steel plate to prevent corrosion and extend its service life. This zinc coated steel plate is called galvanized steel plate.

 

（I）defin

 

PE Water Supply Pipe is coated with a layer of metallic zinc on the surface of the steel plate to prevent corrosion and extend its service life. This zinc coated steel plate is called galvanized steel plate.

 

 

（II）classification

 

Can be divided into the following categories according to production and processing methods

CREDIT

â‘ Hot-dip galvanized steel plate. A thin steel plate is immersed in a molten zinc bath so that a layer of zinc adheres to its surface. It is mainly produced by the continuous galvanizing process, that is, the rolled steel plates are continuously immersed in a plating bath containing molten zinc to make galvanized steel plates;

 

â‘¡Alloyed galvanized steel sheet. This kind of steel plate is also made by the hot dip method, but it is heated to about 500°C immediately after coming out of the tank to form an alloy film of zinc and iron. This kind of galvanized sheet has good paint adhesion and weldability;

 

 

â‘¢Electro-galvanized steel plate. This kind of galvanized steel sheet manufactured by electroplating method has good processability. However, the coating is thin and its corrosion resistance is not as good as that of hot-dip galvanized sheets;

CREDIT

â‘£ Single-sided galvanized steel plate and double-sided galvanized steel plate. Single-sided galvanized steel sheet is a product that is galvanized on only one side. In terms of welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheets. In order to overcome the shortcomings of one side not being coated with zinc, there is another type of galvanized sheet that is coated with a thin layer of zinc on the other side, that is, double-sided galvanized sheet;

 

 

（III）Advantage

 

1. Strong corrosion resistance: Galvanized sheet has good corrosion resistance and can resist most chemical corrosion.

 

2. Good processability: Galvanized sheet has good processability and is easy to cut, shape, weld, etc.

 

3. Long service life: Galvanized sheet has a longer service life, which can extend the service life of steel plates.

 

4. Relatively low price: Compared to high-end materials such as stainless steel, galvanized sheet is more cost-effective.

 

5. Good wear resistance: Due to the excellent hardness and wear resistance of the zinc layer on the surface of galvanized sheet, galvanized sheet can resist mechanical wear to a certain extent.
